The dolphin named Flipper first swam into the world's minds and hearts in this 1963 film starring Chuck Connors and Luke Halpin as Sandy (a role he would continue in the 1964-68 TV series that followed.) James B. Clark, a long-time family filmmaker whose credits include "Island of the Blue Dolphins" and "My Side of the Mountain," directs the story of hard times (Hurricane Hazel and its aftermath) and joy (Sandy's dolphin-powered rides through the waves). And two fins up for Mitzie, the animal star who plays flipper.
